Interesting idea. A single home-user would surely fall under the mentioned
"low volume threshold" of 100.000 units, so it would be interesting to see
if there are any hidden fixed costs. Please post if you do decide to try it.
If nothing else, if someone wants to break the system, a suggestion on
Slashdot for each and every Open-Source user to do so (nomatter whether it
will be granted or not), would probably give them a very tough week in their
sales department. ;)
